We have begun a multi-epoch Spitzer Space Telescope GTO observing campaign of the galaxy M33. M33 is one of the two nearest spiral galaxies, and is oriented at nearly 50 degrees, providing an advantageous viewing angle for a comprehensive survey of its stellar population and the associated chemical evolution of the dust. Our Spitzer observing program involves mapping the galaxy multiple times at intervals of 7, 14, and 21 days, over a period of 2.5 years using both the IRAC 3-8 micron camera and the MIPS 24-160 micron camera. In addition, the mapping program will be followed by Spitzer spectroscopy of select bright novae, HII regions, and variable stars.
Our initial images were taken in late December 2003 and early January 2004 and show unprecedented detail in star formation regions, dusty evolved star shells, HII regions, and red supergiants. We present here our first epoch IRAC and MIPS images as well as SEDs of select sources.
